Don't miss the final full moon of 2025, when the "Cold Moon" takes to the autumn sky at sunset on Dec. 4. Here's how to watch the lunar spectacle unfold online from the comfort of your home thanks to some handy livestreams.
This month's full moon is often known as the "Cold Moon" to reflect the frigid temperatures that are common in the Northern Hemisphere this time of year and also as the "Moon Before Yule," as it is the last full moon before the Christmas period. The lunar milestone will take place as the moon passes within 90% of its closest point to Earth in its monthly orbit — a point known as perigee — giving rise to a beautiful "supermoon" that can be up to 30% brighter and appear 14% larger than the smallest moon of 2025.
